To be honest unless they have a killer idea I'm not sure a Nintendo console can be successful in the modern market context.
They may want to focus first and foremost on the portable, and if there is a second home-only SKU, just make that more of a companion type product.
GameCube was $99 for like half its life cycle and it still only capped out at a rather mediocre 22 million install base. So I dunno if price alone is the solution.
